Medical Xpress / Early signs of Parkinson's can be identified in the blood
A team led by researchers at Chalmers University of Technology, Sweden, has succeeded in identifying biomarkers for Parkinson's disease in its earliest stages, before extensive brain damage has occurred. The biological processes ...
Phys.org / The first direct observation of a liquid charge density wave
Charge density waves (CDWs) are ordered, crystal-like patterns in the arrangement of electrons that spontaneously form inside some solid materials. These patterns can change how electricity flows through materials, in some ...
Phys.org / Cuttlefish use polarized light to create a dramatic mating display invisible to humans
Many organisms leverage showy colors for attracting mates. Because color is a property of light (determined by its wavelength), it is easy for humans to see how these colors are used in animal courting rituals. Less obvious ...
Medical Xpress / Faster to trials? Low-dose THC plus celecoxib improved cognition in Alzheimer's model mice
In recent years, research into cannabis and its main psychoactive ingredient, Δ⁹-tetrahydrocannabinol (THC), has unearthed medical benefits including anti-inflammatory and neuroprotective properties. However, THC is also ...
Phys.org / Saltwater crocodiles traveled thousands of miles across the Indian Ocean, genetic study suggests
Accounts from early expeditions to the Seychelles more than 250 years ago described crocodiles as common along the coasts of the archipelago. But after the first settlers established a permanent presence in 1770, the Seychelles ...
Medical Xpress / Experimental immunotherapy clears harmful artery cells, reducing plaque in mice
Scientists have designed an immunotherapy that reduces plaque in the arteries of mice, presenting a possible new treatment strategy against heart disease. The antibody-based therapy could complement traditional methods of ...
Phys.org / King's Trough: How a shifting plate boundary and hot mantle material shaped an Atlantic mega-canyon
The King's Trough Complex is a several-hundred-kilometer-long, canyon-like system of trenches on the North Atlantic seafloor. Its formation was long thought to be the result of simple stretching of the oceanic crust. An international ...
Phys.org / Crosstalk inside cells helps pathogens evade drugs, study finds
Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings, published in the journal Nature Communications, describe how these mechanisms drive ...
Phys.org / Roadkill offers an ethical alternative to live wildlife in scientific research
A recent review of over 312 studies has identified dozens of unique uses of roadkill in scientific research. The review, published in Biology Letters, discusses the advantages of using roadkill instead of live wildlife and ...
Phys.org / Programmable terahertz vortices enable dual electric and magnetic skyrmion modes
Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns. These structured light vortices, known as skyrmions, are highly stable and resistant to disturbances, ...
Medical Xpress / Hippocampus does more than store memories: It predicts rewards, study finds
A preclinical study published in Nature has found evidence that the hippocampus, the brain region that stores memory, also reorganizes memories to anticipate future outcomes.
Phys.org / Cleaner ship fuel changed clouds, but not their climate balance
To reduce air pollution associated with ocean transport, the International Maritime Organization tightened restrictions on sulfur content in ship fuel, resulting in an 80% reduction in emissions by 2020. That shift created ...
